Its repetitive true, but I enjoy the fights so I'm not bored!
I find the game a bit too easy, right from the start you can crowd control anything. I would have prefered more AC than Batman, especially the fleeing/climbing.
There is no difficulty control, you can only disable HUD help.
When you're out of health you have a "last truggle QTE" which can even become a one-shot finisher with abilities, you never lose health through falling, there is plants everywhere on the map which fully restore your health, its really hard to die in story mode.
Some boss have very good strenghts (invincible to any attacks for example, except backstab) and even improved attack patterns (leaps, combo, grappling, double damage, etc) but the little mobs are hardly challenging (some specials are hard to manage truth be told).
The story is remarkably simple but interesting enough to incent to continue (and the orc society is nicely represented, + a lot of back stories and role playing elements), the number of possible attack pattern is near infinite, there is a lot of reflex based skill to go through battles without a scratch (cRPG players should have no problem) and tons of objectives/missions to do in a very large completely open world.
Overall: greatly entertaining, but the character is a bit too invincible.
Played 4 hours, might have some surprises left for me.
The challenge mode might be a good catch when you're done with the campaign.
